Title: Piezoelectric transformer
Inventor: KAWASAKI OSAMU
IPC: H01L41/107
Filed: 1995-12-27
Abstract: PROBLEM TO BE SOLVED: To obtain an optional mode Rosen-type piezoelectric transformer which is capable of enlarging an input electrode in area so as to be improved in input capacitance enhancing a current which flows into an input electrode even if alternating current signals of low voltage are inputted, and outputting a higher voltage. SOLUTION: A Rosen-type piezoelectric transformer of λ/2 mode is provided with an input electrode formed on its primary surface covering it above half as much in area, whereby the transformer can be enhanced in input capacitance, so that it is lessened in input impedance. A current which flows into an input electrode 1 can be enhanced in quantity even if alternating current signals of low voltage are inputted, so that the piezoelectric transformer is capable of outputting a higher AC voltage. If a step-up circuit is provided, an electromagnetic transformer which is used for stepping up an input AC voltage can be dispensed with.

Title: Liquid crystal display device
Inventor: YOSHIDA YUKIFUMI
IPC: G02F1/1343
Filed: 1995-12-27
Abstract: PROBLEM TO BE SOLVED: To make the gap between both substrates at the periphery of a liquid crystal display element uniform, suppress the generation of display unevenness at the peripheral part, and improve the display quality by nearly equalizing the occupation rate of the area of the wires at the part where a seal material is provided to the area of the seal material on each side of the liquid crystal display element, and making the total numbers of spacers present on the wires uniform respectively. SOLUTION: The seal material 3 at the entire periphery in a frame shape is considered as four divisions on each side of the liquid crystal display element 62 and the total number of spacers present on the wire 1 or 2 at the part on each side where the seal material 3 is provided is made nearly equal. Namely, the width of the seal material 3 is changed by the sides and adjusted so that the occupation rate of the area of the wires at the seal part to the area of the seal material 3 becomes nearly equal. Consequently, the dispersion rate in the seal material 3 is equal, so gap differences are suppressed on the respective sides of the liquid crystal display element 62, i.e., over the entire periphery to obtain a uniform gap, thereby suppressing the generation of display unevenness at the peripheral part of the liquid crystal display element 62.

IPC: G11B20/10
Filed: 1989-12-29
Abstract: PURPOSE:To improve apparent transfer speed from a host device by recording and reproducing data under synchronization among rotational positions and rotational speeds of individual optical disks inserted into plural optical disk drives. CONSTITUTION:A reference synchronizing signal 21 to be a reference for the rotational speed and phase of an optical disk 22 is always sent out by a reference synchronizing signal generating circuit 15 to the individual disk drives 19 and 20, while each sector address is always reproduced by each of the individual optical disk drives 19 and 20 under the loading state of each optical disk 22, and a sector address detecting signal 32 is sent out by an address detecting circuit 30. The sector address detecting signal 32 is compared with the reference synchronizing signal 21 by a motor servo control circuit 31 to control the rotational speed of a disk motor 24 in order to conform each individual period and phase with each other. By this method, the plural optical disk drives are synchronized, and at the same time, the recording and reproducing are thus operated.

Patent JP-H11178262-A (JP)
Title: Rotor of rotating electric machine
Inventor: SENBA AKIOMI
IPC: H02K3/487
Filed: 1997-12-11
Abstract: PROBLEM TO BE SOLVED: To prevent electrolytic corrosion by providing an insulating layer between each wedge and each tooth, insulating the wedges and the teeth from each other completely, and to prevent an overcurrent from flowing between them. SOLUTION: By inserting an insulating layer 6 between each wedge 2 and each tooth 3, a construction which prevents an overcurrent from flowing in and out and electrolytic corrosion from occurring is formed. And a construction free from electrolytic corrosion is formed by making each wedge 2 itself of an insulator in addition, causing overcurrents to flow in the teeth 3, and causing them to flow into a retaining ring through a shrinkage-fitted part at the end part. Consequently, an overcurrent does not flow in and out between each wedge 2 and each end damper ring, and between wedge 2 and each tooth 3, and it is possible to prevent electrolytic corrosion caused by overcurrents induced in the rotor of a generator at the time of a thyristor start, or when higher harmonic currents flow in from a power system.  Consequently, it becomes possible to enhance the endurability and reliability of the generator against its higher harmonic currents.

Filed: 1989-12-28
Abstract: PURPOSE:To easily supply high-frequency electric power to a laser element and to easily monitor a laser-beam output level by a method wherein the ground line of a transmission line is utilized as a monitoring wiring. CONSTITUTION:A surface-side ground electrode 303b is connected not directly to a ground terminal but via a capacitor 40; one side of the surface-side ground electrode 303b is connected to a photodiode 22 for monitoring use and the other side is connected to a monitoring signal terminal M.

A monitoring signal of the photodiode 22 for monitoring use is output to the terminal M through the surface-side ground electrode 303b. Although a high-frequency component of the monitoring signal is lost via the capacitor 40 at this time, a low-frequency component required to detect an average value can be taken out to the terminal M. Thereby, an optical output level can be monitored.
